How to use getPurchases() - Android

[MSP3]

I have successfully implemented In-App-Billing into my app. The IAP is working successfully and I have tested it to make sure its working.

When a user clicks on a button, they have to make an IAP to proceed. However, everytime a user clicks on the button it starts the IAP, even though they have already made the IAP. I want my IAP to be non-consumable obviously. Currently, I'm storing the IAP in SharedPreferences, but if the user reinstalls the app, they lose their IAP.

So how can I use getPurchases() or restoreTransactions() on my onCreate or onClick method to check whether the user has purchases a specific item? I have searched all over the Internet and read through so many samples and it doesn't seem to work, perhaps I am misunderstanding though.

If you need me to post any code, please ask and I'll update my post.

If you do post code, enclose it in [code][/code] tags to make it easily readable in syntax.

but if the user reinstalls the app, they lose their IAP.

If you're storing a record of the user's IAP locally on the device, then a reinstall of the app will completely destroy that data. If you want to retain a permanent record of purchases in this situation, then you'll have to use a remote database to do that.

Hi, thank you for your response. I understand what you're saying thank you. So, perhaps I could use Firebase to store that information

That would do the job.
